Characteristics

Agreement:

Reference level for the relative attenuation arel of the TFS 170 is the minimum of the attenuation amin. The minimum of the

attenuation amin is defined as insertion loss ae. Reference frequency fc is the mean value of the frequencies with a relative

attenuation of 3 dB.
